Experimental Study of Micro Vortex Generator Effects on Lift-drag Characteristics of a Supercritical Airfoil

  • 摘要: 采用低速风洞实验方法,研究了安装在超临界翼型上的微型涡流发生器四种高度和安装位置对绕该翼型的流动影响。对比干净翼型和安装微型涡流发生器的翼型升阻特性,结果表明:同向安装的微型涡流发生器能减小阻力,但对升力和失速迎角影响不大;大尺寸微型涡流发生器减阻没有小尺寸效果好;高度低于0.4δ(δ为边界层名义厚度)的微型涡流发生器最佳安装位置为参考分离位置下游3.5δ~4.5δ处。
